Variation.—The collection of the Bureau of Science contains 
Specimens of this species; my own collection also contains speci- 
mens from various localities. The young, like the young of Rana 
macrodon, differ rather markedly from the adult. In R. magna 
the upper eyelid ig broader than the interorbital distance; the 
tympanum is distinct and not as far from the eye; the tubercles 
and folds on body are less numerous; there is a rather distinct 
broken dorsolateral fold. from eye to above groin (rarely contin- 
uous), and there are other shorter longitudinal folds on the sides; 
the webs on the feet are somewhat excised between the toes; the 
disks on the fingers are slightly more distinct; the tibiotarsal 
articulation reaches variously from eye to tip of snout; the dorso- 
lateral fold is separated from the supratympanic fold. The body 
above is dark brown of varying shades, sometimes with darker 
Spots; groin strongly marked with black; the youngest specimens 
usually have a strong, dark brown temporal spot; labials with 
large brown spots which are continuous on both upper and lower 
Jaws; posterior part of limbs dark, mottled with yellow and 
white; usually a loreal stripe present. 
In the adult specimens the length of the first and fourth 
fingers varies somewhat, Occasionally the first is longer than 
the fourth, frequently shorter; the toes are frequently fully 
webbed, the membrane reaching more than halfway on the toe 
oF pads; the large teeth of the females are low, and not 
Prominent ag in the males; males invariably have small vocal 
“acs, the openings being rather small, back and near the angle of
